JOHN PUTNAM SWAN, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO GENERAL FIREEXTINGUISHER COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF NEWYORK.

PIPE-HANGER.

Specification of Letters Patent.

Patented May 20, 1913.

To all whom it may concern:

Be it known that I, JOHN P. SWAN, a citizen of the United States,residing at Providence, in the county of Providence and State of'RhodeIsland, have invented new and useful Improvements in Pipe- Hangers, ofwhich the following is'a specification.

This invention is intended to provide an improved hanger for supportingthe supply and return pipes of a hot water heating system, one above theother, in such inanner as to provide for the adjustments necessary forgiving them the desired pitch in opposite directions. a

The features of construction and arrangement in Which my inventionreside are hereinafter described in connection with the ac companyingdrawings, in which Figure 1 is a front elevation of one form of thehanger; Fig. 2 is a side elevation of the same, showing the pipessupported thereby; and Fig. 3 is a partial view similar to Fig. 2 butillustrating a slight modification.

The hanger illustrated in Figs. 1 and 2 comprises a supporting bracket-2which is adapted to be rigidly secured to a vertical wall and has anoutwardly-extending arm 3 connected to the vertical portion of thebracket by a strengthening web 4. On opposite sides of said web thehorizontal flanges of the arm 3 are provided with perforations throughwhich pass the threaded upper portions of two pairs of supporting rods 5and 6, one pair on each side of the web a, with adjusting and clampingnuts thereon. At their lower ends said rods 5 and 6 are providedrespectively with hooks 7 and 8 or the like, in which are locatedbearing studs formed on the ends of hori zontal rollers 9 and 10, eachroller being concaved circumferentially at its center in accordance withthe transverse curvature of the pipe to be supported thereby, so as forthe smaller pipe 11 is preferably made shorter than the roller for thelarger pipe 12, and in Fig. 2 is shown the arrangement employed forsupporting the larger pipe above the smaller pipe. In this case the rods5 have the same spacing at their upper ends as the rods 6, so as toleave room between them for the pipe 12, but are bent inward belowsaidpipe to receive the roller 9, while in the modification shown inFig.3, which is employed when the smaller pipe is to be supported above thelarger pipe, the rods 5 which carry the pipe 11 are nearer togetherthroughout their lengths than the rods 6 which carry the pipe 12, beinglocated wholly above the space occupied by the latter pipe.

As thus constructed, the pipes may be readily put in place or removed byfirst removing the rollers 9 and 10 from the hooks which carry them orby sliding the pipes endwise along said rollers, and the varioussupporting rods if made of appropriate lengths may be adjustedvertically to hold the pipes one above the other and give them theslight pitch from end to end which is usually required in practice, sothat a compact and eflicient hanger for the intended purpose isprovided.

I claim as my invention:

A pipe hanger comprising a bracket having a horizontal arm, two pairs ofindependent supporting rods having threaded shanks passing throughopposite edge portions of said arm, respectively, and provided withadjusting nuts, and two pipe supports carried by said pairs of rodsrespectively and-located one above and in ad vance of the other, saidsupporting rods being spaced to receive the lower pipe between the rodsof one pair and the upper pipe between the rods of both pairs.

In testimony whereof, I have hereunto subscribed my name this 29th dayof August, 1911.
